Schur multipliers of unitriangular groups

Group Theory 2013-05-20 v1

Abstract

An explicit formula for the Schur multiplier of the group of unitriangular matrices over products of cyclic rings \ZZ/m\ZZ\ZZ/m\ZZ and \ZZ\ZZ is derived. We use it to provide presentations of the corresponding covering groups and touch upon the question of finding their nonisomorphic representatives.
